The YamlReference package

This package contains "the" reference YAML syntax parser
(Text.Yaml.Reference), generated directly from the YAML
specifications, as well as sample program (yaml2yeast) that
allows accessing it from the command line, converting YAML
files to YEAST tokens. This is intended to be more of an
"executable specification" for YAML rather than an actual
basis for YAML tool chains. That said, it is possible to build
interesting tools on top of it, such as the yeast2html YAML
syntax visualizer (contained in this package), pretty
printers, etc. This is a streaming parser that will
"immediately" begin to generate output. The memory leak that
existed in previous version has been plugged.
